将点云数据进行读取，并获得点云模型的边界特征点(The point cloud data is read, and the boundary feature points of the point cloud model are obtained.)

说明：  矩阵，尤其是分块矩阵的分解，删除，调整，可以方便数值计算，减少冗余(Matrix, in particular, block matrix decomposition, delete, adjust, easy numerical calculation, to reduce redundancy)

tikz manual use of tikz code in latex to draw good circuit diagrams.

说明：  基于遗传算法，进而优化惩罚因子，核函数参数的的支持向量机进行分类(GA SVM classification)

应用matlab程序，实现了对手写数字的识别，准确率非常高。(Matlab application procedures, to achieve the hand-written digit recognition, the accuracy rate is very high.)

模拟直扩系统中加性高斯白噪声信道环境下接受机误码率的计算(DS simulation system additive white Gaussian noise channel environment sets the bit error rate calculation)

说明：  程序使用说明： 1、软件应用平台：Matlab6.5或更高； 2、打开方法： 将文件所在目录设为工作目录，然后打开wavlet.fig,在noise提示框下输入噪声强度，在0-0.1之间（不能为零）。 然后点process按钮，就会显示实验结果，包括原图像，加噪图像，去噪图像的对比以及当前的psnr值。 wavlet.m是程序文件。 程序内容写在在程序的注释里。 阈值的更改没有实现可视化，在源程序中可以改。(Procedure for use: 1, Software Platform: Matlab6.5 or higher 2, open the way: the file directory set the working directory, then open the wavlet.fig, the noise boxes, enter the noise level, in the 0-0.1 between (not zero). Then process the button, it will show the experimental results, including the original image, noise image denoising image contrast and the current psnr value. wavlet.m is the program file. Program content in the program notes written inside. Threshold changes are not visualized in the source program can be changed.)

三角级数法求路面时域模型，并应用pwelch方法求其功率谱密度，与标准路面功率谱密度进行对比(Trigonometric series method for road surface model in time domain, and the application of the pwelch method for its power spectral density, and the standard of pavement power spectral density contrast )
